Where would the evap emission system pressure sensor be on the car
Expert:  Ron Z. replied 1 year ago.
The P0453 points to a problem with the Canister Pressure Sensor. On this vehicle, the pressure sensor is built into and part of the Canister Assembly. The Canister is located under the vehicle, towards the rear. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. Inspect the inlet and vent lines for any cracks, holes or disconnections. If the visual inspection checks ok, replace the Canister Assembly.
